3. Prevention of Electro Static Discharge (ESD) toElectrostatically Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily by static electricity. Suchcomponents commonly are called Electrostatically Sensitive (ES) Devices. Examples of typicalES devices are integrated circuits and some field-effect transistors and semiconductor "chip"components. The following techniques should be used to help reduce the incidence ofcomponent damage caused by electro static discharge (ESD).1. Immediately before handling any semiconductor component orsemiconductor-equipped assembly, drain off any ESD on yourbody by touching a known earth ground. Alternatively, obtain andwear a commercially available discharging ESD wrist strap, whichshould be removed for potential shock reasons prior to applyingpower to the unit under test.2. After removing an electrical assembly equipped with ES devices,place the assembly on a conductive surface such as alminum foil,to prevent electrostatic charge buildup or exposure of theassembly.3. Use only a grounded-tip soldering iron to solder or unsolder ESdevices.4. Use only an anti-static solder removal device. Some solderremoval devices not classified as "anti-static (ESD protected)" cangenerate electrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate5
